User manual
The USB controller is configured using the following registers:
This chapter describes the OTG and I
controller which integrates the (OHCI) host controller, device controller, and I
interface (Master only) controls an external OTG transceiver.
USB OTG (On-The-Go) is a supplement to the USB 2.0 specification that augments the
capability of existing mobile devices and USB peripherals by adding host functionality for
connection to USB peripherals. The specification and more information on USB OTG can
be found on the USB Implementers Forum web site.
The architecture of the USB OTG controller is shown below in the block diagram.
The host, device, OTG, and I2C controllers can be programmed through the register
interface. The OTG controller enables dynamic switching between host and device roles
through the HNP protocol. One port may be connected to an external OTG transceiver to
